PINEAPPLE-GOREB IN A PINEAPPLE CORING AND SLICING MACHINE.

Specification of Letters Patent.

Patented June 8, 1915.

Original application filed October 12, 1914, Serial No. 866,330. Dividedand this application filed February 18, 1915. Serial No. 9,024.

To all whom z't may concern:

Be it known that I, FRED W. VVOLF, a citizen of the United States,residing at Honolulu, island of Oahu, Territory of Hawaii, have inventeda new and useful Pineapple- Gorer in a Pineapple Goring and SlicingMachine, of which the following is a specification.

This application is a division of my application filed October 12, 1914,Serial No. 866,330, for pineapple coring and slicing machine.

The object of the invention covered by the present application istheprovision of novel coring means and novel means for holding thepineapple during the coring operation and subsequentl Y to discharge it.I attain these and other objects of my invention as hereinafter morefully disclosed, by the mechanism illustrated in the accompanyingdrawings, in which I Figure l is a side elevation of my machine; Fig. 2is a top plan of the machine; Fig. 3 is an enlarged detailed sectionalview of the turret showing the means for'holding the pineapple duringthe coring; and Fig. 4 is a detail sectional View of the coring means online 44 of Fig. 3; Fig. 5 is a detail of member 48.

Like characters of reference indicate like parts throughout the severalviews.

Referring to the accompanying drawings, mounted on a suitable supportingframe I provide a main driving shaft 2, operated by pulley 1 and clutch3. Mounted on the main driving shaft 2 is a bevel gear 4 meshing withbevel gear 5 on an upright shaft 7, which is supported by bracket 6.Mounted on the upper end of the shaft 7 is a crank disk 8, to which issecured a pitman 9. The opposite end of the pitman 9 is connected tocrosshead 10, the latter being slidable on guide rods 11, which aresupported by castings 12 on the frame, as illustrated in Figs. 1 and 2.Crosshead 10 in turn operates coring tube 40. On main driving shaft 2are keyed disks 13 and 14, between which is mounted a locking hub 15.Inserted in disks. 13 and 14 is a pin (not illustrated) which operatesGeneva wheel 17, which is keyed on turret shaft 18. Mounted on turretshaft 18 is the turret 19, which, as illustrated, is composed of novelhooked, starpointed plates or disks 20, spaced apart one from the otherby offset ribs 21. The series of disks 20 are held together by bolts 23and hub members 22 which bolts 23 fasten together. The series of disks20 revolve between two turret castings 25 which are mounted on the mainframework of the machine. Suitable means (not illustrated) are providedto prevent hub members 22 from becoming too tight.

Rotatably mounted on top of the turret castings, as shown at 31 in Fig.3 is a shaft 32 to which is attached a curved plate member 33. It has apivotal or swinging movement when shaft 32 is partially rotated. To theend of shaft 32 is attached a cam lever 34, to the lower end of which isattached a spring (not illustrated), which in turnis fastened to theframe of the machine so as to hold the member 34 in tension against acam 36 mounted on the main driving shaft 2. WVhile the fruit is beingcored it is held in the pocket formed between the hooked star ends ofthe turret plates or disks 20 by plate 33. A stationary cover plate 37is fastened to the turret castings 25 forward of the flap or cover plate33.

Pineapple coring tube 40, carried by crosshead 10, is supported bycastings 12. It is reciprocated by the crosshead to core the pineapplesat intervals when the turret is stationary, intervening between itsintermittent movements. An inner sleeve guard 41 encircling coring tube40 is mounted between casting 12 and turret casting 25. Goring tube 40has a sharpened mouth 42. For the reception of the mouth 42 of coringtube 40 I provide a coring knife guide 43. This member has an annulargroove 44 which encircles a central core 45, over which the mouth of thecoring tube 40 projects as it completes its coring stroke, thuspreventing dulling of the sharpened mouth 42 and pushing the coredportion of the pineapple farther into the coring tube, and ultimatelydischarging successive cores from the opposite end of the coring tube.An outer sleeve guard 48 (shown with part broken away, in Figs. 1 and 2,only a small portion of the member being shown) projects from the end ofthe frame to protect the outer end of coring tube 40. This is shown indetail in Fig. 5.

In operation, the pineapples, which have previously been suitablyprepared (pared and trimmed), are fed into the turret by suitable meanssuch as chute A and received in the pocket, as at B in Fig. 4, betweensuc- V the turret revolves step by step, regulated by the Geneva wheel17, until it reaches the coring position, indicated by C. lVhile theshaft 2 is making one revolution, the Geneva wheel 17 and the turret 19are moved forward one step or pocket and then locked in a temporarilyfixed position by locking hub 15 engaging with the curved surface of theGeneva Wheel 17 The crank diskS is so timed with the main driving shaft2 that the coring tube is pushed through the fruit while the turret islocked or stationary, the fruit being held by plate 32. After the coringoperation the next step or movement of the turret 19 brings thepineapple in contact with means for slicing the pineapple, set forth inmy original application, iereinbefore referred to. The pineapples remainin a horizontal position throughout the coring and slicing operations.

What I claim is:

1. In a pineapple machine, the combination of an intermittentlyrevoluble turret adapted to retain fruit in a stationary horizontalposition during the coring operation,

a horizontally slidable coring tube to core Copies 01' this patent maybe obtained for the fruit while in a stationary position, horizontallyactuated reciprocating means driving the coring tube, and tubularprotecting members within which the coring tube travels. V v

2. In a machine of the class described, the combination of a revolubleturret consisting of spaced plates having hooked, fruit-engaging starends to retain the fruit in horizontal position, a pivotally mountedcurved plate intermittently engaging over the fruit to retain it in afixed position, a reciprocating coring tube positioned to core the'fruitWhile engaged by the aforesaid plate, and means for actuating the coringtube to core the fruit during the interval that it is in stationaryposition, substantially as set forth.

3. In a pineapple machine, a revoluble turret having a plurality ofhooked star end portions to convey the fruit, adjustable 'meansengageable over the fruit to retain it in a fixedposition relative tothe portion of the turret in which it is disposed, and means for coringthe fruit when thus retained.

In testimony whereof, I hereunto affix my signature in the presence oftwo witnesses.
